|1.||Your Mum's abortion was a fail.|
Following the "your mum" trend, this comeback can be used in most situations. Completely meaningless but completely amazing to use. Basically meaning, your mum had an abortion, but it failed and your still here. "Your dad's condom was a fail." is also appropriate.
"That was a fail."
"Your mum's abortion was a fail."
(Can be replaced with "Your dads condom..")
